Deconfinement and Chiral Symmetry Restoration
We discuss the critical behaviour of strongly interacting matter close to the QCD phase transition. Emphasis is put on a presentation of results from lattice calculations that illustrate deconfining as well as chiral symmetry restoring features of the phase transition. We show that both transitions coincide in QCD while they fall apart in an SU(3) gauge theory coupled to adjoint fermions. We al...
متن کاملDeconfinement and Chiral Symmetry Restoration
We illustrate why color deconfines when chiral symmetry is restored in gauge theories with quarks in the fundamental representation, and while these transitions do not need to coincide when quarks are in the adjoint representation, entanglement between them is still present. Introduction. One of the long-standing puzzles in theoretical physics is the relation between confinement and chiral symm...
متن کاملChiral Symmetry Restoration in Hadron
The evidence and the theoretical justification of chiral symmetry restoration in high-lying hadrons is presented. I. CHIRAL SYMMETRY RESTORATION OF THE SECOND KIND It has recently been suggested that the parity doublet structure seen in the spectrum of highly excited baryons may be due to effective chiral symmetry restoration for these states [1]. This phenomenon can be understood in very gener...
متن کاملConnection between Chiral Symmetry Restoration and Deconfinement
We propose a simple explanation for the connection between chiral symmetry restoration and deconfinement in QCD at high temperature. Both spontaneous chiral symmetry breaking and confinement are generated by the condensate of a color octet quark-antiquark pair. The transition to the high temperature state proceeds by the melting of this condensate. For instanton-dominated effective multiquark i...
متن کاملIsospin breaking and chiral symmetry restoration
We analyze quark condensates and chiral (scalar) susceptibilities including isospin-breaking effects at finite temperature T. These include mu md contributions as well as electromagnetic (e 0) corrections, both treated in a consistent chiral Lagrangian framework to leading order in SUð2Þ and SUð3Þ chiral perturbation theory, so that our predictions are model-independent. The chiral restoration ...
